Tuya WR3 Smart Siren

rudy12767 · May 25, 2024, 1:16pm

I’ve been able to flash the Tuya WR3 module using LibreTiny. I’ll post the .yaml to make the siren and leds work.

esphome:
  name: alarm
  friendly_name: alarm

rtl87xx:
  board: wr3

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

  

ota:
  password: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

wifi:
  ssid:xxx
  password: xxx

switch:
  - platform: restart
    name: "Alarm Restart"
  - platform: gpio
    pin: PA05
    name: "Lichtje"
    id: Lichtje
 
sensor:
    - platform: wifi_signal
      name: "Alarm-wifi"

output:
  - platform: libretiny_pwm
    pin: PA12
    frequency: 2600 Hz
    id: pwm_output


light:
  - platform: monochromatic
    output: pwm_output
    name: "Sirene"
    id: Sirene
button:
- platform: template
  name: "Alarm-buzzer"
  on_press:
  - script.execute: buzzer_five

script: 
- id: buzzer_five # Use the same buzzer name you have given above. 
  then:
    - repeat:
          count: 10
          then:
             - light.turn_on: Sirene
            - switch.turn_on: Lichtje
            - delay: 500ms                
            - light.turn_off: Sirene
            - switch.turn_off: Lichtje
            - delay: 1000ms

Do you have some more details how to flash the WR3 Smart Siren?

There’s the information you need.

After a lot of attemps I’ve been able to flash the wr3 chip with esphome. It was difficult for me to place the chip in download mode. Anyway thanks a lot for your esphome config.

I’ve added one of the buttons (PairOnOff) to the esphome config:

binary_sensor:
  - platform: gpio
    name: PairOnOff
    pin:
      number: PA15
      inverted: true
      mode:
        input: true

I’m in the same boat . Found the siren while looking for something else, thought it would be a 5 min job with a CP2102 but can’t get it into download mode.

And yes, this is also done.

connect CEN to GND
connect TX2 to GND
release CEN from GND
release TX2 from GND

This is what I get:

I’m a bit rusty, so can anyone point me to the right direction?

EDIT:
Spoke too soon. The weird part is, that I only reconncted TXD to GND and didn’t use CEN at all now. Suddenly flashing worked…Weird.

All is working well! Thanks @rudy12767 for sharing the YAML file and @dinant for the addition!
